Title: Sliding reducer seal for surgical trocar
Inventor: USCHOLD ROBERT C
IPC: A61B17/34
Filed: 1995-03-23
Abstract: A reducer seal which fits within the cannula handle of the trocar.  Contained on the reducer seal there is a seal retainer.  Contained on the seal retainer there is a track and movable on the track there is a slide.   The reducer track is attached to the trocar housing.   The reducer seal retainer is attached to the slide and holds the reducer seal in place.  The reducer slide then snaps onto the reducer track.  In an "open" position the reducer slide  is  held  away  from an  opening  in the  reducer. Detents on the reducer track hold the reducer in this position.   Transverse motion moves the reducer into an active or "closed" position.  The reducer seal slides into frictional  engagement  on  the  sealing  surface  of  the reducer track.     The reducer has a smaller diameter opening than the trocar cannula.

Title: Backpulse piston assembly for crossflow filters
Inventor: BOWMAN RONALD W
IPC: B01D65/02
Filed: 1995-06-07
Abstract: A  filtration  system  including a crossflow filter having an interior  membrane  and  a backpulse piston-and-cylinder assembly having  a  first  port  connected  to  a  permeate  outlet of the crossflow  filter  and  a  second port positioned at a different location  than  the first port.  The piston-and-cylinder assembly has  an interior piston movable between a first position blocking fluid  flow  between  the  first  port  and the second port and a second  position  permitting  fluid  flow  between  the first and second  ports.    An actuator is connected to the piston so as to move  the  piston from the second position to the first position.          The  piston defines an interior chamber within the assembly.  The first  port  and  the second port are in fluid communication with the  interior  chamber when the piston is in the second position.    A  controller  is  connected  to  the  actuator  for  causing the movement  of  the  piston  relative  to  a temporal event or to a pressure   differential across  the  interior  membrane  of  the crossflow filter.

Title: Collapsible lobster trap
Inventor: WASS ERIC C
IPC: A01K69/10
Filed: 1995-06-16
Abstract: A collapsible lobster trap having an external and internal design very similar to existing, non-collapsible traps, which allows a user to transport by truck, boat, or other means, a larger number of traps per excursion than is currently possible. The trap has a rectangular bottom panel to which a first pair of opposed side panels and a second pair of opposed side panels are hingedly attached. A top panel is hingedly attached to one of the side panels and is secured in the closed position by two retaining straps. In a preferred embodiment of the invention, each panel of one pair of opposed side panels is designed with ends overlapping the ends of the other pair of opposed side panels so that the vertical corners of the trap are structurally reinforced while maintaining collapsibility. The trap has two internal partitions made of a net-like material in the form of a funnel shape with the larger opening of the funnel shape being attached to the bottom and long sides of the trap and the smaller opening of the funnel shape attached to the sides of the trap creating multiple compartments. The long side panels each have an entrance opening also made of similar, net-like material forming a funnel to the inside of the trap. The partitions and the entrance openings are of such a design so as to make it extremely difficult for lobsters to escape. An alternative design that omits interior components results in a device suitable for storing such marine creatures when in use, and that is collapsible for easy storage when not in use.

Abstract: A method is provided herein for producing a variety of re-formed and saltcured herring roe mixed foods including "herring roe on kelp", "herring roe on shellfish" and "herring roe with kamaboko" by making the best use of the intrinsic binding ability of fresh herring eggs. In one embodiment, the method may begin by extracting ovaries from sexually-matured herring. Individual eggs are then singled out from the ovaries. The eggs are rinsed and cleaned. A perforate mould is then filled in single or multi-layers with any solid food or foods, e.g., kelp, fish, shell-fish, kamaboko, ham, sausage and/or cheese between the layers of eggs, to form a sandwich structure. The sandwich structure in the mould is then salt-cured, substantially to the saturation level. The salt-cured and solidified product is then removed form the mould. The so-produced product also forms part of the present invention.

Filed: 1995-03-16
Abstract: Une barrette coulée pour un accumulateur plomb-acide est réalisée en alliage à base de plomb comprenant essentiellement environ 2,5 à 3,5 % en poids d'antimoine, environ 0,01 à 0,5 % en poids d'arsenic, environ 0,01 à 0,5 % en poids d'étain, environ 0,008 à 0,1 % en poids de sélénium, le reste étant du plomb. La teneur en au moins un des trois éléments arsenic, étain et sélénium, se situe dans la plage suivante: environ 0,075 à 0,5 % en poids d'étain, environ 0,1 à 0,5 % en poids d'arsenic, et 0,021 à 0,03 % en poids de sélénium. Dans le cas des alliages à base de plomb contenant de l'antimoine, de l'arsenic, de l'étain et du sélénium, des additions plus importantes d'antimoine, d'arsenic et de sélénium ont généralement un effet favorable sur la résistance à la corrosion à long terme de barrettes d'accumulateur utilisées dans un environnement d'accumulateur plomb-acide, tandis que l'étain a un effet défavorable dans la mesure où des quantités plus importantes d'étain diminuent considérablement la résistance à la corrosion à haute température. Les effets défavorables de l'étain sur la résistance à la corrosion sont modérés par l'ajustement des niveaux des trois autres éléments, en particulier de l'arsenic, qui peut fournir un niveau d'augmentation prévisible de la résistance à la corrosion pour une teneur en arsenic donnée. Une famille d'alliages très bien adaptée à l'utilisation dans les barrettes d'accumulateur coulées et dans les barrettes de raccordement a été développée sur la base de ces rapports.
